IPC-1752A: Materials Declaration Management

Overview

IPC-1752A is the electronics industry's common machine-readable form. A supplier uses it to tell a customer what substances and materials are inside a part.

Key point

It is one XML format with two flavours. A compliance declaration answers whether the part meets RoHS or REACH. A full material declaration reports every substance. Both declare against lists like the IEC 62474 DSL.

Why it exists

Manufacturers must prove products meet rules like RoHS and REACH, which requires composition data from every supplier. IPC-1752A defines one structured format everyone can produce and consume, so data flows up the chain and tools can validate it automatically.

How the data flows

A declaration turns scattered supplier knowledge into a validated file the customer can act on. The same pattern works for electronics, articles, or conflict minerals.

1Supplier knows composition

What substances and materials are in the part, down to the homogeneous material.

2Encode as IPC-1752A XML

A compliance declaration or a full material declaration, against the right substance list.

3Requester validates

The customer ingests and schema-validates the XML automatically, with no re-keying.

4Roll up and prove

Data aggregates across suppliers into compliance evidence for the finished product.

Key concepts

Requester / Supplier. Data flows from the supplier, who knows the composition, to the requester, who needs it.
Two form types.
1. A substance / compliance declaration reports compliance to lists like RoHS, REACH SVHC and JIG, plus which listed substances are present.
2. A Full Material Declaration (FMD) gives a complete breakdown down to the homogeneous material level.
Declaration classes (Class 1 to 6). Disclosure increases by class, from administrative info only up to a full material declaration.

Data format

It is XML-based, with a published schema for automatic validation.
It was originally delivered as an Adobe PDF form with embedded XML. Modern platforms generate and ingest the XML directly.
It carries substance identities by CAS number, mass or percentage, regulatory lists, and exemptions claimed.

How it relates to other standards

It is part of the IPC-175x family. IPC-1754 extends the same approach to aerospace, defense and other articles.
It can declare against the IEC 62474 Declarable Substance List, which harmonizes what must be reported.
